TECHNICAL FIELD

The present invention relates to an exercise method and an exercise device for performing an exercise suitable for thigh and hip muscles such as fitness equipment and an exercise bicycle, and more particularly to an exercise method and an exercise device for strengthening thigh and hip muscles by performing a movement of lowering legs and then moving the legs backward or putting the legs together or apart from a position of pulling the legs toward a chest of the user with an arm disposed between the legs in a sitting or lying position of the user. In addition, the present invention relates to a leg exercise device including a trajectory measuring device of generating motion range information of the exercise device and making the motion range information as data through a motion range measurement sensor attached to knee and hip joints of the user seated on the exercise device, smart device and an application of the smart device.

BACKGROUND ART

In general, as illustrated in FIG. 1 , an exercise for strengthening thigh and hip muscles is performed by pulling legs toward a chest and compressing the legs to the outside by using a pelvis as an axis. However, since a typical exercise method and an exercise device directly transmit a load to an ankle and a knee, ankle and knee joints may be damaged, and a person having weak ankle and knee joints may not perform the exercise method.

In addition, a typical bicycle that is generally used by a knee patient has been developed to go faster more distance with a less force. Thus, as illustrated in FIG. 2 , since the bicycle has a pivot axis disposed around an ankle, an exercise is concentrated on lower legs and gives a small effect on upper legs and a hip joint. Thus, a prior bicycle of this inventor expand an exercise range suitable for a motion range of knee joints and the hip joint and increase the exercise effect to be used for exercises.

Specifically, the prior invention of the inventor expands a motion range of the hip joint and the knees by arranging an arm pivot axis of the prior exercise device in parallel to the hip joint in a corresponding manner in order to use the bicycle for exercises.

Also, as a foot plate or a foot pad of the exercise device connected to a weight is positioned on a thigh of an exercising leg, and a movement of raising the exercising leg toward a chest and rotating the leg backward in a sitting or lying position of the user is performed, a force transmitted to the knee and the ankle decreases.

DISCLOSURE OF THE INVENTION Technical Problem

As illustrated in FIG. 2 , a typical fixed-type bicycle that is generally used by a user who has a weak knee has an insignificant effect of strengthening a hip joint because a motion range of the hip joint is restricted, and an axis of a movement is fixed (an exercise range of about 10 to 20). As illustrated in FIG. 1 , a general motion range of the hip joint of a human is about 120°. Thus, the prior invention of this inventor expands the motion range such that a pivot axis of an exercise device is disposed parallel to a position of a hip joint of a body of a user, and the user performs an exercise of lowering thighs and moving the thighs backward from a start position of pulling the thighs to a chest of the user. However, the exercise device according to the above-described invention shows a few problems. Thus, technical objects will be described below.

First, the exercise device according to the invention has inconvenience in that the user is necessary to change a seat position during exercises when a single arm and a single pivot part are provided so that a seat does not disturb rotation of the arm, and a pivot axis of the arm corresponds to a hip joint (first problem).

Second, a motion range of a knee and a hip joint is necessary to be changed for each injured portion for rehabilitation treatment. For example, the cruciate ligament tear has a knee motion range that becomes opposite according to whether the portion is anterior or posterior. Also, the motion range of a hip joint exercise is changed for a patient with spinal disc herniation according to injured portions. However, the exercise device according to the prior invention is not suitable for patients with spinal disc herniation, anterior cruciate ligament rupture, and posterior cruciate ligament rupture because the motion range of the hip joint exercise is 120° or more of a normal person (second problem). Thus, an effective rehabilitation exercise device capable of selecting the exercise motion range according to a body state of a patient.

Third, the prior exercise device, in which the pivot axis and the hip joint are disposed parallel to perform a movement of lowering legs and moving the legs backward from a start position in which the user sits on the seat, places the legs on one end of the arm, and pulls the legs toward the chest of the user, causes discomfort because a length of the arm of the exercise device contacting the body is changed according to a rotation angle of the hip joint or the knee joint. For example, a distance from the pivot axis to the pedal decreases when the legs are raised, and the distance increases when the legs are lowered. However, a length of the arm is fixed to cause discomfort. Also, knees are over-bent or over-extended to generate side effects (third problem). Thus, the length of the arm is necessary to be varied according to the variation of the length of the leg to the pivot axis.

Fourth, the exercise device according to the prior invention causes discomfort because the pedal rotates by using a bar as an axis when a foot is placed on the pedal to perform a linear movement.

Fifth, in case of a typical bicycle, the arm rotates by 360° to automatically move from an exercise end section to an exercise start section. In case of the exercise device according to the prior invention, the exercise section is within 180°, the arm does not returned from the end section to the start section.

Sixth, in case of an axis conversion device of the exercise device according to the prior invention, when a roller connected to a resistance body is hinged from x-axis parallel to the ground to a y-axis perpendicular to the ground, the roller is easily worn because a wire is not fixed to the roller, and thus the wire hits the roller.

Seventh, the exercise device according to the prior invention requires expensive manufacturing costs because each of a y-axis pivot axis connected to the arm and a bevel gear set is provided in plurality and is easily broken as a volume of a gear device increases.

Eighth, the exercise device according to the prior invention may not perform a basic leg muscle resistance exercise such as squat, lunge, and deadlift. In case of the exercise device according to the prior invention, a handle hits the body of the user like an exercise device suitable for the thigh and hip muscles such as a total hip machine.

Ninth, the exercise device according to the prior invention may perform a leg exercise, but may not perform an upper body exercise.

Tenth, the exercise device according to the prior invention occupies a wide space when stored indoor.

Technical Solution

In order to solve the first problem, an exercise device according to the present invention is configured such that as an arm slides within a guiding range of a guiding rail 2, and the guiding rail 2 is disposed between both legs of a user when viewed on a plan view, a seat 4 and the arm are not overlapped with each other although the user does not change a position of the seat 4, and two arm pivot parts are not provided to both sides (KR 20-2020-0001877).

In order to solve the second problem, the exercise device according to the present invention attaches a sensor to adjust an exercise range according to a state of a body of a patient, thereby selecting an exercise range according to characteristics of disease (KR 10-2021-0029110, KR 10-2021-0044071).-deleted-

In order to solve the third problem, the exercise device according to the present invention performs a movement in which a portion of the body connected to the arm rotates and simultaneously compresses by providing a shock absorber to the arm having one end connected to a pivot axis and allows a length of the arm to be extended and then restored through the shock absorber when a length of legs are changed according to a rotation angle. The shock absorber may have a gas cylinder shape and apply a resistive force by a spring in addition to gases (KR 10-2021-0040066).

In order to solve the fourth problem, the exercise device according to the present invention is configured such that as a pipe and a bar that linearly moves in the pipe are provided to the arm instead of the shock absorber, a portion of the body connected to the arm rotates and simultaneously compresses, and the length of the arm is extended and then restored to an original state through the pipe and a bar 11 that linearly moves in the pipe. In addition, as a second pipe 22 connected parallel to the pipe is provided, a second bar 21 is provided in the second pipe, and a second bar fixing body 20 is provided on the bar, when the bar linearly moves from the inside to the outside of the pipe, the second bar also linearly moves from the inside to the outside of the pipe, so that the pedal does not rotate about the bar (KR 10-2021-0046163, KR 10-2021-0046813). Through the above-described invention, an effect of simultaneously performing a rotation exercise and a compression exercise is generated.

In order to solve the fifth problem, the exercise device according to the present invention is configured such that as the axis is separated into a left side and a right side, and the left and right sides are organically connected by using a gear and a roller, the exercise device is returned from an exercise end section to an exercise start section (KR 20-2020-0152414).

In order to solve the sixth problem, the exercise device according to the present invention is configured to move on an x-axis parallel to the ground and rotate on a y-axis perpendicular to the ground by using a spiral gear or a bevel gear. In addition, as the gear device is manufactured to have a gear box shape, a user may attach the gear device to an existing exercise device in order to recycle the existing exercise device. Furthermore, as a time belt, a belt, and a sprocket are inserted into a pipe having a rectangular shape or a pipe shape provided below the seat, a belt pulley or a sprocket is connected to the gear device according to the present invention, and the belt pulley is connected to a resistive body of the existing bicycle (KR 10-2020-0152414, KR 10-2020-0153238).

However, the exercise device requires expensive manufacturing costs because each of a y-axis pivot axis connected to the arm and a bevel gear set is provided in plurality and is easily broken as a volume of the gear device increases. Thus, in order to solve the seventh problem, the exercise device according to the present invention reduces the size of the gear box to reduce the manufacturing costs-deleted-(KR 10-2020-0170941, 10-2020-0179121, 10-2021-0002955, KR 10-2020-0179121).

In order to solve the eighth problem, the exercise device according to the present invention includes a handle angle adjusting device for adjusting an angle of a handle of the exercise device to adjust a position of the handle, so that the handle does not contact the body of the user when performing lunge, squat, or deadlift (KR 10-2021-0058860).

In order to solve the ninth problem, the exercise device according to the present invention couples the exercise device with an upper body complex exercise device (KR 10-2021-0046813).-deleted-

In order to solve the tenth problem, the exercise device according to the present invention make the exercise device in the form of a desk or a chair to be used as furniture when the exercise device is not used for exercises. In addition, in order to solve the tenth problem, the exercise device according to the present invention includes a simple band (KR 20-2020-0001795).

Advantageous Effects

Hereinafter, advantageous effects of the present invention will be described.

Second, as the sensor is attached to the exercise device, a doctor or a trainer may monitor the exercise motion range of the user, and the exercise record of the user may be made as data to be used for preparing an exercise program and contributed on medical development. Also, as the exercise record may be real-time transmitted to a mobile device, individuals may be connected to share the exercise record or perform a competition, thereby increasing the exercise effects (KR 10-2021-0029110, 10-2021-0044071).-deleted-

Third, the exercise device according to the present invention increases the exercise effect by applying the rotational force and the compressional force in a complex manner and performs the exercise similar to the natural movement, and when the user performs the exercise of pulling the legs toward the chest and then lowering the legs and rotating backward through the movement in which the bar linearly moves in the pipe, the length of the arm is flexibly extended and then automatically restored according to the substantial variation of the legs contacting the arm during the hip joint pivot exercise (KR 10-2021-0040066).

Fourth, the pedal may not rotate about the bar during exercises (KR 10-2021-0046163, KR 10-2021-0046813).-deleted-

Fifth, the left and right arms of the exercise device organically rotate by using the roller and are automatically restored from the exercise end section to the exercise start section.

Sixth, the gear device moves on the x-axis parallel to the ground or rotates on the y-axis perpendicular to the ground by using the bevel gear or the spiral gear to solve the phenomenon of abrasion of the wire connected to the roller, and the resistive body of the existing bicycle may be used by attaching the gear device to the existing bicycle to solidify the technology of the exercise device according to the prior invention and recycle the existing bicycle (KR 10-2020-0152414,KR 10-2020-0153238, KR 10-2020-0163490).

Seventh, the exercise device according to the present invention reduces the size of the gear box to reduce the manufacturing costs (KR 10-2020-0170941, KR 10-2020-0179121, KR 10-2021-0002955).

Eighth, the exercise device according to the present invention includes the handle angle adjusting device for adjusting the angle of the handle, so that the handle is not brought into contact with the body of the user when performing lunge, squat, or deadlift (KR 10-2021-0058860).

Ninth, the exercise device is coupled with the upper body complex exercise device to perform the upper body exercise in addition to the lower body exercise (KR 10-2021-0046813).-deleted-

Tenth, the exercise device is provided in the form of the desk or the chair to be used as furniture when the exercise device is not used (KR 10-2021-0035113). Also, the exercise device is provided in the simple band shape to be easily stored (KR 20-2020-0001795).-deleted-

As a result, the user who have the weak knee and ankle joints or the user who wants to strengthen the thigh and hip muscles without strain of the joints may perform the thigh and hip muscle strengthening exercise by using the exercise method and the exercise device to strength the muscles, ultimately reduce the risk of disease such as diabetes, prevent obesity, and promote health after the middle age. Also, the present invention helps to aesthetically shape the body and athletes to improve the sports ability without strain of the knee and ankle joints.

Hereinafter, an embodiment of a quads and gluteus exercise of the present invention to achieve the above-described objects will be described in detail with reference to the accompanying drawings.

In order to resolve a first problem of the technical object, as illustrated in FIGS. 3 to 8 (KR 20-2020-0001877), an exercise device of the present invention, which performs an exercise suitable for a quads and gluteus exercise, may include: a frame 1; a seat 4 connected to the frame 1 and allowing a user to have a sitting or lying position; a guiding rail 2 connected to the frame 1; a slide arm 3 slidingly moving with a guiding range of the guiding rail 2; and a leg pad pivotably connected to one end of the slide arm 3 and disposed below legs of the user or disposed to contact a rear surface of the legs of the user.

Also, as the slide arm 3 and the guiding rail 2 are provided so that the slide arm 3 moves along the guiding rail 2 to allow the slide arm 3 to rotate about a pivot axis disposed in a hip joint of the user, the pivot axis of the slide arm 3 rotating along the guiding rail 2 may be disposed corresponding to the hip joint of the user, and as the guiding rail 2 is disposed between both legs of the user when viewed on a plan view as illustrated in FIG. 5 , the user may perform a movement in which the user sitting or lying on the seat 4 puts both the legs on the leg pads and alternately lowers the legs and moves the legs backward from a start position in which the legs are pulled toward the user's chest.

Preferably, the leg pad is necessary to be disposed on a rear surface of a thigh of the user to protect knees and ankle joints of the user. Also, as illustrated in FIGS. 3, 4, 6, and 7 , a foot plate or a pedal may be connected to one end of the leg pad.

In addition, preferably, as illustrated in FIG. 8 , the exercise device may be configured to adjust suitably for a portion of a user's body that the user wants to exercise as the guiding rail 2 connected to the frame 1 includes an axis conversion part that converts the guiding rail in a direction of a X-pivot axis parallel to the ground (FIGS. 3, 4, and 5 ), in a direction of a y-pivot axis perpendicular to the ground (FIGS. 6, 7, and 8 ), and in a diagonal direction when an angle to the ground is 45°.

The guiding rail 2 may be disposed perpendicularly to the frame 1 as illustrated in FIGS. 3, 4, and 5 or pivotably provided horizontally to the frame 1 as illustrated in FIGS. 6, 7, and 8 , and the axis conversion part may include a fixing unit 6 for fixing the guiding rail 2 to the frame 1. Thus, the user may selectively perform a rotation movement of selectively lowering the legs and moving the legs backward from the start position in which the legs are pulled toward the user's chest, a movement of spreading both the legs apart and then putting the legs together as illustrated in FIG. 6 , or a movement of spreading the legs from the start position of putting the legs together as illustrated in FIG. 7 .

Preferably, the exercise device of the present invention may include a resistive force generator for generating a resistive force against pivoting of the slide arm 3. The resistive force generator may use a method of using a physical friction such as a tension of a belt and a magnetic drum and include a fluid resistor or a block box connected with a pneumatic pressure, a circular plate, and a wire.

The sensor unit that senses a feature of the exercise of the user is disposed at the arm or the pivot axis. The control unit allows the user to receive contents communicating through a predetermined network with a mobile device or a computer. The communication unit transmits data of the sensor unit to the control unit or the contents of the control unit to the sensor unit.

FIG. 10 is a schematic conceptual view illustrating the exercise device according to an embodiment of the present invention for explaining a position at which an angle sensor is attached. As illustrated in FIG. 10 (KR 10-2021-0044071), the exercise device according to the present invention includes a pivot axis motion range measurement sensor b1 disposed at a position corresponding to the hip joint of the user and a pivot axis motion range measurement sensor b2 disposed at a position corresponding to the knees of the user. The motion range measurement sensor may be disposed at the pivot axis, the arm, or the pedal.-deleted-

The motion range measurement sensor may include: a core; an input coil wound around one side of the core and forming a time-varying magnetic field as a time-varying current is applied; an output coil spaced a predetermined distance from and parallel to the input coil and inducing a voltage caused by the time-varying magnetic field generated from the input coil; and a pivot body pivotably installed between the input coil and the output coil and in which a moving object is coupled to a pivot axis thereof. The pivot body may be a conductive circular plate shaped structure, which has an outer circumferential shape in which a radius increases linearly or in the form of a predetermined function when pivoted and in which a portion is disposed in parallel between the input coil and the output coil, and a central pivot axis thereof is disposed outside of the input coil and the output coil. Also, the pivot body may be an angle sensor using an electromagnetic induction method for measuring a pivot angle of the moving object coupled to the pivot axis of the pivot body by detecting a variation of a magnitude of a voltage induced to the output coil according to a variation of a radius of the circular plate when the pivot body performs a pivoting movement. The above-described technology is disclosed in Korean Patent Registration No. b10-0856b24b26.-deleted-

The motion range measurement sensor may have a module type attached to and detached from a substantially exercising portion (e.g., a wheel shaft of a cycling device or a stepper device or a pedal of a bicycle or a stepper, which is deviated from a predetermined range of a pivot center instead of a pivot axis) of the exercise device that repeatedly performs a reciprocating movement or a circular movement. The motion range measurement sensor may include an acceleration sensor and a gyro sensor of three axes, which respectively detect an acceleration and an angular speed in directions of the three axes.-deleted-

The sensor may be connected to a smartphone through a wired or wireless communication including Bluetooth and appropriately process the detected motion range as a signal to count the number of effective exercises and transmit this information to a computer or a smartphone.-deleted-

In addition, the sensor may count the number of exercises by calculating values of the acceleration and the angular speed detected by installing the acceleration sensor and the gyro sensor to a pivot axis of the hip joint and a pivot axis of the knee joint and transmit the exercise information to the smartphone. The above-described technology is disclosed in Korean Patent Registration No. b10-b2049506.-deleted-

FIG. 11 is a schematic diagram representing the exercise device including the motion range measurement sensor according to the present invention. A trainer and a doctor who is the user may monitor the exercise motion range according to a degree and a wounded portion that is a physical characteristic of a patient by using this exercise device and make the exercise motion range as data. Also, the user himself or herself may perform a rehabilitation exercise by controlling an exercise range through real-time monitoring.-deleted-

In order to resolve a third problem of the technical object, as illustrated in FIGS. 12 to 18 (KR10-2021-0040066), the exercise device according to the present invention may include: a frame 1; a handle 7 connected to the frame 1; a seat 4 connected to the frame 1; a pivot axis 11 connected to the frame 1 and disposed in parallel to the hip joint of the user; an arm 10 connected to the pivot axis; and a shock absorber 12 connected to the arm. The exercise device may allow a user to perform an exercise similar to a natural movement of a body of the user by pivoting a portion of a body connected to the arm and simultaneously performing a compression movement, and may be flexibly extended in length and automatically restored based on a different in body length caused by folding and unfolding of the hip joint and knees of he user by installing the shock absorber.-deleted-

The shock absorber may apply a resistive force to the inside thereof by pressing, hydraulic pressure, and spring elasticity according to the typical technology. The shock absorber may be contracted and then extended or extended and then contracted on the contrary. Preferably, the shock absorber may be integrated with the arm or arranged linearly with the arm when viewed on a sagittal plane.

In addition, a muscle resistance according to the pivot exercise may increase by connecting a resistance body to the pivot axis. When an embodiment of the present invention is used as an indoor bicycle, a motion range of the bicycle may be extended, and an exercise effect may increase.

Also, an exercise device of the related art in which a pivot axis of an arm is disposed parallel to the hip joint or the knees causes inconvenience because the arm of the exercise device, which contacts a body according to a pivot angle of the hip joint or the knees, has a constant length. For example, since a distance from the pivot axis to the pedal decreases when legs are raised, and the distance increases when the legs are lowered, the fixed length of the arm causes inconvenience, and the knees are over-bent or over-extended to cause side effects. However, in the present invention, the distance may be flexibly extended and then automatically restored according to the difference of the body length when folded and unfolded by installing the shock absorber.

In order to resolve the third problem of the technical object, as illustrated in FIG. 18 (KR 10-2021-0046163), the exercise device according to the present invention may include: a frame 1; a handle 7 connected to the frame; a seat 4 connected to the frame; a pivot axis 11 connected to the frame 1; an arm 10 pivotably connected to the pivot axis; a pipe 12 a having a straight line shape and disposed linearly to the arm; and a bar 12 b having a straight line shape and disposed inside the pipe to vertically move. Here, as the pedal is connected to the bar 12 b, the user may perform a movement of raising the legs toward the chest and then pivoting the legs around the hip joint and simultaneously pulling and compressing the legs in a state in which the user put the legs on the pedal. Through this, as the rotation exercise and the compression exercise are simultaneously performed, the exercise similar to the natural movement of the body may be performed, and when the user sits on the seat to raise the legs toward the chest and then lower the legs and pivot the legs backward through the linear movement of the bar in the pipe, the length of the arm may be flexibly extended and then automatically restored according to the substantial variation in length of the legs contacting the arm caused by the pivoting exercise of the hip joint.

According to a typical technology through a pipe 12 a and the bar 12 b disposed in the pipe, the resistive force may decrease by the inner pneumatic pressure or hydraulic pressure or the spring elasticity, and the pipe 12 a and the bar 12 b may be contracted and then extended or extended and then contracted on the contrary. Also, a muscle resistance according to the pivot exercise may increase by connecting a resistance body to the pivot axis.

When an embodiment of the present invention is used as an indoor bicycle, a motion range of the bicycle may be extended, and an exercise effect may increase.

In order to resolve a fourth problem of the technical object, as illustrated in FIG. 18 (KR 10-2021-0046163), the exercise device according to the present invention may include: a second pipe connected in parallel to the pipe; a second bar disposed in the second pipe; and a second bar fixing body disposed on the bar, so that the pedal does not rotate around the bar as the second bar linearly moves to the outside from the inside of the second pipe when the bar linearly moves to the outside form the inside of the pipe. Thus, when the user performs a compression exercise from a start position of putting the legs on the pedal and pulling the legs, the pedal may linearly moves instead of rotating. In addition, as illustrated in FIGS. 55 and 56 (KR 10-2021-0046813), the pedal may not rotate around the pipe by selectively providing a guide rail to the pipe and a roller to the bar and selectively forming a groove in the bar or cutting one surface of the bar and providing a projection on the pipe.

In order to resolve a fifth problem of the technical object, as illustrated in FIGS. 19 to 27 , the exercise device according to the present invention may include a gear device allowing left and right arms of the exercise device to organically rotate by using the gear and the roller and be automatically restored from an exercise ending position to the start pose, and to move on the axis parallel to the ground or rotate around the axis perpendicular to the ground, and as the gear device is attached to an existing bicycle to use a resistive body of the existing bicycle, the technology of the exercise device according to the related art may be realized, and the existing bicycle may be recycled. FIGS. 19 and 20 are views illustrating an axis conversion gear box according to an embodiment of the present invention, and FIGS. 21 and 22 are views illustrating a state in which the axis conversion gear box is attached to an indoor bicycle according to an embodiment of the present invention.

Hereinafter, a description on the well-known technology will be omitted.

As illustrated in FIGS. 28 to 36 (KR 10-2020-0163490), the axis conversion gear device according to the present invention may include the arm attached onto a x-axis parallel to the ground and simultaneously attached onto the y-axis perpendicular to the ground. Since the axis conversion gear device according to the present invention may include the arm attached onto the x-axis parallel to the ground as illustrated in FIG. 29 and simultaneously attached onto the y-axis perpendicular to the ground as illustrated in FIG. 30 , the user may selectively perform a movement of lowering the legs and moving the legs backward or a movement of putting the legs together. A leg pad may be disposed below the thigh of the user as illustrated in FIGS. 31 and 34 (15 a) or disposed below of the legs of the user as illustrated in FIG. 35 (15 b). The leg pad may have a “

” -shape as illustrated in FIGS. 32 and 34 or a “

” -shape as illustrated in FIG. 36 .
